The BRCA genes are involved in initiating DNA repair and cell cycle check points, they as as regulators of other tumour supressors genes such as p53 and help the cell repair and damage which may lead to cancer occurring in the cell.
In mutant versions of the BRCA genes they cannot perform their roles and damaged DNA may cause the cell to replicate uncontrollably as check point to prevent this has been removed. Genome stabiliy is affected and cancer can develop
What else can I help you with?
Are person's characteritsics determined only by genes?
physical characteristics, yes. unless there was a mutation at birth
Is the source of brand new genes in a population called mutation?
Yes, brand new genes can only come from mutation.
What does mutation means?
Mutates-- Undergoes a spontaneous change in the make-up of genes or chromosomes.
How does different genes happen?
New genes appear in individuals by random mutation.
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
Jumping gene occur in what type of mutation?
Jumping genes are a type of mutation known as transposition. This mutation involves the movement of genetic material from one part of the genome to another, potentially causing disruptions or changes in gene function.
What is a non polar mutation?
a mutation in a gene that does not affect the downstream genes in an operon. ie. a polar mutation is one that DOES affect the transcription or translation of genes in the same operon downstream of your gene of interest.
Why are the white tigers white?
It is a mutation of genetic genes.
What are Stability Genes?
Stability genes are one of the three main genes, that when mutated are associated with cell progression towards tumorigenicity. It's normal function is to control the rate of mutation, but if mutated it off-balances, effecting oncogene and tumor suppressor function. In other words, accelerating the mutation process.
What is the most common mutation to genes?
p53 gene..approximately 50% of human cancers involve this mutation.
Is mutation the same as successful reproduction?
A mutation is basically a change in genes. They may be good or bad. A good mutation is also known as an adaptation.
Functional unit of mutation is muton?
The functional unit of mutation is actually the nucleotide. A mutation is a change in the sequence of nucleotides in DNA, which can lead to changes in the genetic code and potentially affect the expression of genes or the function of proteins. The muton is a term that refers to the smallest unit of DNA that can undergo mutation, which is typically a single nucleotide or a small number of nucleotides.
